In a display panel and a display device having the display panel, the display device has a first pixel area, a second pixel area, a third pixel area and a fourth pixel area. A red fluorescent member, a green fluorescent member and a yellow fluorescent member are formed in the first pixel area, the second pixel area and the third pixel area. The red fluorescent member emits a red light by using a blue light incident thereon. The green fluorescent member emits a green light by using a blue light incident thereon. The yellow fluorescent member emits a white light by using a blue light incident thereon. A blue light incident on the fourth pixel area passes through the fourth pixel area so that the blue light is irradiated from the fourth pixel area.
